Saltwater shore bashing

The Christmas season is now upon us, many anglers will begin to pursue popular inshore species such as East Australian Salmon, Silver Trevally, Black Bream and Sand Flathead. Fishing from the shore has been one of my favourite methods of targeting specific species of fish for some time now and the very thought of discovering a new location is enough for me leave the boat at home. With Georges Bay and some North West hot spots being my favourite places to fish, many other destinations have either been discovered or successfully fished. Typical locations such as Red Rock on the North West coast has been producing many different species for a while now with the captures of good sized Silver Trevally, Gummy Sharks, Elephant Fish and Southern Garfish becoming more common. Some people worry and stress about not being able to access a kayak or boat in order to venture out onto the water but in reality, most anglers will have at least two great fishing spots that they can easily access from the shore.
When I began fishing from Red Rock on the North West coast with my good mate Jeremy Shaw, the possibility of encountering a Draughtboard Shark or Eagle Ray was enough to keep us coming back each weekend. Many days were spent fishing at Red Rock with colossal amounts of burley and junk food. Back then, captures of small East Australian Salmon and Sand Flathead were cherished and we never thought of leaving the rock for any reason other than the occasional trip out in the boat for a Mako Shark. During at least five years of fishing from Red Rock, we caught numerous and memorable fish including that of a rather large Seven Gilled Shark. It wasn’t until I began to seriously fish around the plentiful beaches and jetties of Georges Bay that I realized that fishing was the thing for me. Like the many hobbies that people enjoy, I got better at the sport and eventually became unstoppable. I believe that every angler needs to start off somewhere, land based fishing is a great way to begin the life long journey.Read more ...

Tasmania's Beautiful Brookies

by Greg French

Brook trout, with their olive backs, lemon spots and, in the case of spawners, bright orange flanks are perhaps the most strikingly beautiful of all salmonoids and, because they are so rare in Australia and New Zealand, most anglers aspire to catch one. While the species does not offer the same challenge as the ever cunning brown trout, it is highly regarded in its native North America and we are privileged to have a couple of wild populations in Tasmania.

 

Why are brook trout so rare?
Throughout Australia and New Zealand brookies have found it almost impossible to compete with other salmonoids. Releases of hatchery reared fry, fingerlings or adults into existing brown trout and rainbow trout waters often result in reasonable fishing for one or two seasons but natural spawning, if it occurs at all, is ultimately unsuccessful.

Even established brook trout only fisheries have collapsed once other trout have been introduced. Late last century (probably in 1889) Lake Leake was stocked with brookies and it seems that a viable wild fishery was maintained until shortly after the introduction of rainbow trout in 1904. The subsequent collapse of the brook trout fishery is hardly surprising given that, even in the USA and Canada, browns and rainbows have caused the demise of countless native brook trout populations.

In Tasmania there have been several attempts to maintain put and take fisheries (waters where fishing is maintained by regular stocking). Impoundments such as Briseis Hole, Vaucluse Reservoir, Edgar Pond and Lake Dulverton, not to mention a number of farm dams, yielded good fish and were reasonably productive but there was a great difficulty in producing regular and worthwhile supplies of hatchery reared stock and the programs were eventually dropped. In recent years the emphasis has shifted towards establishing viable wild fisheries.

Rearing in hatcheries
In the colder parts of North America brook trout have long been recognised as one of the easiest salmonoids to raise in captivity. This success has not been repeated in Australia. All brook trout currently in Tasmania are derived from an importation of 50 000 eyed ova which arrived from Nova ScotiaCanada) in 1962. From this single batch an adequate quantity of healthy fish were reared to maturity, though it was noted at the time that many hatchlings were frail and/or deformed. (

From the outset there has been an undersupply of ova. The number of brood stock which can be held at the Salmon Ponds hatchery is limited and the quality of eggs and milt has always been poor. Better ova can be obtained from wild fish but locating spawners is both difficult and labour intensive.

The poor survival of ova and fry proved to be an ongoing problem. Even today, despite significant advances in aquaculture technology, some 90-95% of ova fails to hatch compared with less than 2% for brown trout ova collected from wild spawners. Furthermore, 50% or more of the sac fry die before the swim up stage and significant losses continue until the time of release. Consequently, maintaining annual stocks of fingerling brook trout is both labour intensive and impossible to guarantee.

Many of the brood fish at Salmon Ponds would be fifteenth generation hatchery reared descendants from the original 1962 importation. Given that the hatchery population has on occasion been reduced to just a handful of adults, it had long been suspected that the stock was inbred and inferior. However, live ova and adults have occasionally been transported to the hatchery from the wild population at Clarence Lagoon and recent research has shown that, not only are Tasmanian brookies essentially very healthy, but they display an extraordinary amount of genetic diversity, even more than can be detected in our wild brown trout.

The problems with hatchery ova may simply relate to warm water which probably affects the development of eggs and milt prior to spawning as well as the progress of newly fertilized ova. This augers well for the long-term well being of the two fisheries in Tasmania where natural recruitment is known to occur.

Spawning and Growth
Since brook trout prefer cold water, they do best in headwater streams and alpine lakes. Even within their native range, sea runs are confined to icy rivers on the east coast if Canada. The most robust populations occur in alkaline (non acidic) water. Spawners prefer shallow streams with low flows and are especially attracted to spring waters and cold up-wellings, though successful lakeshore spawning occurs in some fisheries (including Lake Emily in the South Island of New Zealand).

It is common for brook trout to mature early, males in their first year and females in their second. Fish that have spawned lost strength and, where food and space are limited, they find it difficult to compete with the immature population. Consequently, brook trout from over populated creeks are often extremely stunted. In fact the fish I have taken from several tiny creeks in New Zealand have averaged no more than 120 or 150 mm. Nonetheless, in waters where competition is low, brook trout can grow faster than is normal for wither browns or rainbows. In Tasmania and New Zealand lake fish commonly attain 2 kg or so and occasionally exceed 4 kg. The biggest brook trout ever taken may well be the 14 ½ lb, monster taken from the NipigonRiver in Ontario in 1916.

The Anthony lakes
The Anthony Power development was approved by State Parliament in 1983 and was completed in 1994. As the were to be built on river systems that had remained inaccessible to brown and rainbow trout, the IFC decided to trial brook trout. Although the waters are tannin stained, acidic and hardly ideal for the species, significant natural recruitment has occurred since 1986 when the first fingerlings and adults were liberated into the natural streams and lakes. At present stocking is ongoing but the wild population appears to be robust.

Of the hydro impoundments the only water of interest to anglers is the main storage, Lake Plimsoll. This 47 m deep lake, completed in 1993, suffers dramatic fluctuations in water level, but supports plenty of good-sized fish and is probably the most productive wild brook trout fishery in Australia and New Zealand.

Lake Rolleston is a large natural lake located about 2 km upstream of Plimsoll. It is a headwater lake but natural spawning occurs in its sizable outflow and in several of its small tributary creeks. Fish to 2 kg and more are relatively common. Access is via 6 km of rough vehicular track. The other fishery of note is Lake Selina. This small water lies at the head of a minor tributary creek, 15 minutes walk from the western shore of Lake Plimsoll. Spawning is mediocre and the fishing, though very good at times, is probably largely maintained by artificial stocking.

Clarence Lagoon
This small headwater lake, accessible by vehicular track east of Derwent Bridge, was first stocked with 600 fingerlings in 1963. Natural recruitment is modest and since 1979, when the IFC discovered that the fishery was in delicate balance, the wild stock has been regularly complimented with releases of hatchery reared fry and fingerlings. The fishing can be very good but waxes and wanes according to seasonal factors and the intensity of stocking.

Tactics for Tasmanian brookies
Statistically, brook trout are much easier to catch than either browns or rainbows. This does not mean that the angler is guaranteed success. In Tasmania, at least, the fishing tends to be something of a feast or famine affair.

While brook trout will take food from the surface and occasionally rise well, they appear to be more predisposed than other trout to feeding from the bottom. This behaviour is exacerbated because in summer the fish tend to avoid warm surface water.

Undoubtedly the most consistent lure fishing occurs during rough cold conditions early and lake in the season. In warmer, calmer weather it pays to concentrate your fishing at dawn and dusk. In deeper waters, such as Plimsoll and Rolleston, fishing deep may be advantageous.

For the fly enthusiast persistent prospecting with a wet is the most likely way to catch an exclusive brookie or two. All shorelines produce fish, but hot spots are in the currents of inflows and outflows. As with spinning and trolling, the biggest bags are taken in Spring and Autumn, most commonly during periods of low light. Quite often in April you will find pre-spawners milling about in the shallows, especially in areas adjacent to the mouths of the main spawning creeks. Daytime risers are suckers for a big dry (try a Red Tag or Royal Wulff) and even respond well to bulky wet flies. At dusk, Sloane-style Fur Flies and corks are all you will ever need. You are most likely to find fish rising shortly after a liberation of fingerlings (from Christmas to late April). These fish are usually very small (under 300 g) and should be released. Adult fish rise infrequently buy provide memorable sport when they do. I have found the odd fish working on beetles and spinners as early as September, but the best fishing has always been during summer when the air has been warm and still. The very best action I have encountered has been post Christmas in the Anthony lakes during the mudeye migrations.

Mind you, the rise remains quite unpredictable and locals seem to prefer fishing for browns and rainbows at Lake Burbury where success is all but guaranteed.

All of the Tasmanian brook trout fisheries are tea coloured and none provide exceptional polaroiding. However, Clarence Lagoon can become quite clear when levels are low and at such times proficient scanning is the surest way to succeed. Fast accurate presentations ahead of faint shadows and flickers of white-tipped fins bring certain responses.

Lake Selina features some very good looking polaroiding water, and those fish which stray into the shallow water are indeed easy to spot, but unfortunately most fish prefer to feed offshore.
